Recently found a lump in the small hollow triangle area at the base of the neck which becomes visible and moves up and down when swallowing. I’ve been to my gp and seen a locum who was less than helpful stating they couldn’t feel anything but didn’t actually go anywhere near the area of the lump. Has anyone experienced this in a similar sort of area. Think I need to go back to the gp again but feel like I’m going to get fobbed off again
